Vagina Probe with Brush

ABSTRACT

A sampling probe, having a housing, with a flange at housing&#39;s proximal end, and an internal step ring including a protruding follower tab toward housing&#39;s distal end. The sampling probe further includes a shaft inside the housing, with a brush at shaft&#39;s distal end and a handle at shaft&#39;s proximal end. The shaft includes a solid proximal section, and a spirally grooved distal section, engaging the housing&#39;s follower tab. A retracting compression spring is positioned on the spirally grooved distal section of the shaft inside the housing. With the sampling probe distally inserted in a vagina canal for a Pap smear, pushing the shaft handle distally, the brush at the end of the shaft protrudes out of the housing rotationally, taking a cell sample, followed by the retracting compression spring retracting the brush back into the housing when the shaft handle is released, completing the Pap smear.

RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119 to U.S.Provisional Application No. 62/395,934 filed on Sep. 16, 2016, theentire contents of which are incorporated herein by reference.

FIELD OF DISCLOSURE

The present disclosure relates to medical collection devices andprocedures, and in particular, to medical collection devices andprocedures for conducting a Pap smear test.

BACKGROUND OF THE DISCLOSURE

The Papanicolaou test, also called Pap smear, Pap test, cervical smear,or smear test, is a screening test comprising taking samples fromcervical cells (or vaginal cells if the patient had hysterectomy and islacking a cervix) to detect potential premalignant and malignant(cancerous) processes in the cervix (and also vagina in case ofhysterectomy,) which is located at the upper end of vaginal canal. Thisprocess also can be used to detect the cause of the cancer, which isHuman Papilloma virus, which is a sexually transmitted virus, as well asother sexually transmitted infections like Gonorrhea, chlamydiatrachomatis and Trichomona vaginalis, which are the main infections,which if untreated, can cause pelvic inflammatory disease that can causefemale infertility. Some types of this virus cause genital warts.

A Pap smear test presently is accomplished by using a cell extractiondevice such as a Pap smear spatula and Pap smear brush or alternativelyby a Pap smear broom. In general, a medical practitioner first inserts aspeculum into the woman's vagina, spreading the vagina open, allowingaccess to the cervix. When using a spatula and a brush, the medicalpractitioner then collects a sample of the cells from the outer openingof the cervix by scraping it with the spatula. Alternatively the medicalpractitioner may choose to use a plastic-fronded broom (Pap smear broom)instead of the spatula and brush. The cells are removed from the cervixat the end of vaginal canal (or from vaginal walls, if patient hadhysterectomy) and are checked in a laboratory under microscope forabnormalities.

The test is an effective, widely used method for early detection ofpre-cancer and cancer cells in cervix (or vagina, if patient hadhysterectomy). The test may also detect serious sexually transmitteddiseases like Human Papilloma virus, Neiseria Gonorrhea, ChlamydiaTrachomatis and Trichomona Vaginalis. Therefore, the test may detectabnormalities and infections in vagina, cervix and endometrium.

One of the difficulties with present method for conducting a Pap smeartest is the use of a speculum for spreading the vagina open. Using aspeculum in general is uncomfortable for the patient and may cause pain,and in particular it may prove very painful for young female patients orpost-menopausal patients with significant atrophy and dry tissue wherePap smear may break the tissue causing pain and bleeding and a verytraumatic experience to them, as well as rape victims who want to stayanonymous and do not want to seek medical care. The discomfort may be toa point where patients may avoid the Pap smear test, which may lead tonot detecting the early stage of cancerous processes at a point wherethe cancer may be effectively treated. Also early detection of commonsexually transmitted disease and on time treatment may prevent seriouspelvic inflammatory disease and infertility in affected women.Furthermore, use of a speculum and a spatula and a brush or a Pap smearbroom with the correct procedure usually requires application of thesemedical collection devices by a medically trained physician or nurse. Inrural areas medical facilities and medical personnel and specializedlaboratories may not be readily available. In some instances visiting agynecologist may not be financially accessible for some patients.

What is needed is a better device and method for conducting a Pap smear.

SUMMARY OF THE DISCLOSURE

To alleviate the discomfort or potential injury and accompanying painthat may be caused by a regular Pap smear exam, and also in order toprovide access to a Pap smear test in remote areas where specialistmedical providers are not available, and/or provide the option of aprivate anonymous Pap smear test and follow-on associated lab test, thisdisclosure details a sampling probe that can be used by a medicalprovider on a patient or by a patient herself in taking Pap smear testsamples where the lab test can be done remotely and/or anonymously.

In one embodiment a sampling probe is disclosed, including a housing andan internal shaft with a brush at a distal end of the shaft and a shafthandle at a proximal end of the shaft. The sampling probe furtherincluding a retracting compression spring inside the housing over theshaft keeping the distal end of the shaft and coupled brush inside thehousing. The shaft further having a spirally grooved distal sectionengaged by a follower tab at a distal end of housing, where when theshaft handle is pushed for the brush to protrude out of the housing totake Pap smear samples, with the sampling probe inside a vagina canal,the brush protrude the housing rotating. Following the brush taking thePap smear sample cells, in absence of pressure on the shaft handle thebrush is retracted back inside the housing.

The sampling probe may have different housing configuration including asingle housing or a two part housing to be elaborated on, in thedetailed description section of this disclosure.

The sampling probe further includes a cap with a preservative liquidthat is coupled to the distal end of the housing, whether the one piecehousing or a distal section of the two pieces housing, preserving thePap smear sample to be tested in a lab.

The sampling probe disclosed herein is used for taking vaginal orcervical samples for either Pap smear purposes or sexually transmitteddiseases.

In another embodiment a method for taking a cervical or vaginal sample(for patient with hysterectomy) for the purpose of Pap smear ordetecting certain sexually transmitted diseases is detailed as using onehand, distally inserting a sampling probe into a vaginal canal. Here thesampling probe comprises a housing, a shaft, inside the housing, with ahandle at proximal end of the shaft and a spiral groove at the shaft'sdistal section, and a brush coupled to the distal end of the shaft. Thesampling probe further includes a retracting compression spring insidethe housing on the distal section of the shaft, with the shaft's grooveengaging a follower tab at the distal end of the housing. The Pap smeartest further includes pushing on the shaft handle, against theretracting compression spring, causing the brush to protrude from thedistal end of the housing while rotating, and taking a Pap smear sample.After a sample is taken, the shaft handle is released, causing theretracting compression spring to retract the brush into the housing.

Following the Pap smear test a cap containing preservative liquid iscoupled to the distal end of the sampling probe housing to preserve thePap smear sample to be tested.

When a two sections housing sampling probe is employed for Pap smear,the cap with preservative liquid is coupled to the distal section of thetwo piece housing, preserving the Pap smear sample for testing.

Another method for preserving the Pap smear sample for lab test includesinserting the sampling probe brush into a vial containing a preservativeliquid for preserving the Pap smear sample, then removing the samplingprobe brush from the vial, sealing the vial and sending the vial to alab for testing the Pap smear sample in the preservative liquid.

DETAILED DESCRIPTION

Disclosed embodiments will now be described more fully hereinafter withreference to the accompanying drawings, in which some, but not all ofthe disclosed embodiments are shown. Several different embodiments areprovided and should not be construed as limiting the application of thedisclosure to the details of construction and arrangement of thecomponents or method of use set forth in the following description orillustrated in the following drawings as to the embodiments set forthherein. Rather, these embodiments are provided so that this disclosurewill be thorough and fully convey the scope of the disclosure to thoseskilled in the art.

The present disclosure describes a sampling probe 100 that is used by aphysician on a patient or by a patient herself for examining and takingcell samples from body cavities. In particular the disclosed samplingprobe 100 is used for taking cervical samples or vaginal samples forpatient with hysterectomy for the purpose of Pap smear or detectingcertain sexually transmitted diseases.

In one embodiment, a sampling probe 100 device includes a housing 200with a proximal 228 end and a distal 226 end. The housing 200 furtherincludes a flange 202 at its proximal 228 end, and an internal step ring204 including a protruding follower tab 206 toward its distal 226 end.

The sampling probe 100 further includes a shaft 208 inside the housing200 with a proximal 228 end and a distal 226 end. The shaft 208 includesa brush 242 at its distal 226 end and a handle 210 at its proximal 228end. The shaft 208 further includes a solid proximal section 212, and aspirally grooved distal section 214, where the housing 200 protrudingfollower tab 206 engages the spiral groove 218 of the shaft 208. Thespirally grooved distal section 214 of the shaft 208 includes a shortstraight groove 216 at the distal 226 end of the shaft 208 followed bythe spiral groove 218 around the shaft 208.

The sampling probe 100 further includes a retracting compression spring900 inside the housing 200 positioned on the spirally grooved distalsection 214 of the shaft 208.

As for the configuration of the shaft 208, the solid proximal section212 of the shaft 208 has a diameter that is larger than the innerdiameter of the housing 200 internal step ring 204, and is smaller thanthe internal diameter of the housing 200. Furthermore, the distalgrooved section 214 of the shaft 208 has a diameter smaller than theinner diameter of the housing 200 internal step ring 204.

As for the positioning of the retracting compression spring 900 insidethe housing 200, the proximal 228 end of the retracting compressionspring 900 is in contact with the distal 226 end of the solid proximalsection 212 of the shaft 208 and the distal 226 end of the retractingcompression spring 900 is in contact with the housing 200 internal stepring 204. This positioning of the retracting compression spring 900forces the shaft 208 in its proximal direction 228, where absent anyforce on the shaft 208 handle 210, the brush 242 at the distal 226 endof the shaft 208 remains inside the housing 200.

The brush 242 at the distal 226 end of the shaft 208 includes a brushbristles section 222 and a brush base section 220. A threaded stud 700protrudes out of the brush base section 220 and couples the brush 242 toa threaded blind hole 400 at the distal 226 end of the spirally grooveddistal section 214 of the shaft 208. Furthermore, there is an O-ring 224on the brush base section 220, which is compressed between the outerdiameter of the brush base section 220 and the inner diameter of thehousing 200.

In another embodiment of the sampling probe 100, a bi-sectional housing500 comprises a two sections configuration with a short distal section504 detachably coupled to a long proximal section 502. Here the shortdistal section 504 has a coupling external thread 508 on its proximalend, and the long proximal section 502 has an internal thread 506 on itsdistal end, enabling coupling of the short distal section 504 to thelong proximal section 502 of the bi-sectional housing 500. In thisconfiguration the long proximal section 502 of the bi-sectional housing500 includes the internal step ring 204. Furthermore in thisconfiguration when the two bi-sectional housing 500 sections areseparated the brush 242 detaches from the shaft 208 and remains in theshort distal section 504 of the bi-sectional housing 500.

Furthermore, in the two sections housing 500 embodiment of the samplingprobe 100 a cap 234 with an open end, a closed end, and an O-ring 236 atits open end couples to the distal 226 end of the separated short distalsection 504 of the bi-sectional housing 500 and is configured to hold apreserving liquid 238 to preserve a sample probed by the sampling probe100.

As with the first embodiment of a one piece housing 200 sampling probe100, a cap 234 with an open end, a closed end, and an O-ring 236 at itsopen end couples to the distal 226 end of the housing 200 and isconfigured to hold a preserving liquid 238 to preserve a sample probedby the sampling probe 100.

The sampling probe 100 housing 200, and 500, shaft 208, brush basesection 220, and cap 234 are made of material comprising plastic, metal,ceramic, glass or a combination thereof. Depending of the material usedto make the sampling probe 100 housing 200, and 500, shaft 208, brushbase section 220, and cap 234 the manufacturing method comprise,injection molding, machining, casting, other suitable manufacturingmethods or a combination thereof. The Brush 242 bristles 222 materialcomprise plastic bristles, polyester strands, natural material such asanimal hair, human hair, cotton, any other suitable strands, or acombination thereof. The section of the brush 242 where the bristles 222are coupled to, which has a hemispherical dome shape in hemisphericalbrush 710 and a cylindrical rod shape in the cylindrical brush 800 maybe a soft and elastic material or it may be a hard or plastic materialincluding plastic, metal, ceramic, glass, or other suitable material.

The sampling probe 100 disclosed herein is used for taking vaginal orcervical samples for either Pap smear purposes or sexually transmitteddiseases.

Furthermore, the Pap smear sampling from the vagina canal using thesampling probe 100 is accomplished by using one hand for holding thesampling probe 100, inserting the sampling probe 100 distally inside thevagina canal toward cervix, pushing the shaft 208 handle 210 against theretracting compression spring 900, causing the brush 242 to rotationally230 exit the distal 226 end of the sampling probe 100 housing 200 in aforward movement 232 direction, and releasing the shaft 208 handle 210retracting the brush 242 into the sampling probe 100 housing 200.

In another embodiment a method for taking a cervical or vaginal samplefor patient with hysterectomy for the purpose of Pap smear or detectingcertain sexually transmitted diseases, is detailed as distally insertinga sampling probe 100 into a vaginal canal. Here the sampling probe 100comprise a housing 200 with a distal 226 internal step ring 204including a protruding follower tab 206, an internal shaft 208 with ahandle 210 at the shaft's proximal 228 end and a spiral groove 218 atthe shaft's distal 226 section, a retracting compression spring 900inside the housing 200 on the spirally grooved distal section 214 of theshaft 208, with the housing 200 protruding follower tab 206 engaging thespiral groove 218 of the shaft 208, and a brush 242 coupled to thedistal 226 end of the shaft 208. The Pap smear further includes pushingon the shaft 208 handle 210, against the retracting compression spring900, causing the brush 242 to protrude the distal 226 end of the housing200, with the housing 200 follower tab 206 engaging the shaft 208 spiralgroove 218, causing the shaft 208 and the coupled brush 242 to rotate230 while moving in a forward direction 232 and take a Pap smear sample.After a sample is taken the shaft 208 handle 210 is released, causingthe retracting compression spring 900 to retract the brush 242 into thehousing 200.

After the sample is taken a cap 234 is coupled to the distal 226 end ofthe sampling probe housing 200, with the cap 234 comprising an open end,a closed end, and an O-ring 236 at the cap's open end, and containing apreservative liquid 238 for preserving the Pap smear sample. Then thecapped sampling probe 240 is sent to a lab for testing the Pap smearsample on the brush 242.

In this embodiment the brush 242 includes a base 220 at its proximal 228end and bristles 222 at its distal 226 end, an O-ring 224 at brush'sbase 220, with the O-ring 224 compressed between the brush's base 220outer diameter and an internal diameter of the sampling probe 100housing 200 distal 226 end, where this brush 242 configuration incombination with the cap 234 configuration on the sampling probe 100contains the Pap smear sample and preservative liquid 238 of the cap 234from leaking into the proximal 228 end of the sampling probe 100.

When a two sections housing 500 sampling probe 100 is employed for Papsmear, where the sampling probe 100 bi-sectional housing 500 includes atwo sections configuration with a short distal section 504 detachablycoupled to a long proximal section 502, and the long proximal section502 includes the internal step ring 204. When the two bi-sectionalhousing 500 sections are separated the brush 242 remains in the shortdistal section 504, and the detached short distal section 504 of thesampling probe 100 bi-sectional housing 500 with the brush 242 is capped600. Here the cap 234 contains the preservative liquid 238 and the caped600 short distal section 504 end of the bi-sectional housing 500 withthe brush 242 is sent to a lab for testing the Pap smear sample on thebrush 242.

Another method for preserving the Pap smear sample for lab test includesinserting the sampling probe 100 brush 242 into a vial 1100 containing apreservative liquid 238 for preserving the Pap smear sample, thenremoving the sampling probe 100 brush 242 from the vial 1100, sealingthe vial 1100 and sending the vial 1100 to a lab for testing the Papsmear sample in the preservative liquid 238.

As a method for performing the Pap smear, the holding the sampling probe100, distally inserting the sampling probe 100 into the vagina canal,pushing on the shaft 208 handle 210 and releasing the shaft 208 handle210 is done using one hand.

In yet another embodiment of present disclosure a business method isdisclosed. The business method includes providing a sampling probe t100o a customer for a fee, for taking a Pap smear sample by distallyinserting the sampling probe 100 into a vaginal canal. The samplingprobe 100 here includes a housing 200 with a distal 226 internal stepring 204 including a protruding follower tab 206, an internal shaft 208with a handle 210 at the shaft's proximal 228 end and a spiral groove218 at the shaft's distal 226 section, a retracting compression spring900 inside the housing 200 on the spirally grooved distal section 214 ofthe shaft 208, with the housing 200 protruding follower tab 206 engagingthe spiral groove 218 of the shaft 208, and a brush 242 coupled to thedistal 226 end of the shaft 208.

The business method further includes receiving a used sampling probe 100from the customer and testing the Pap smear sample, or arranging for alab to receive the used sampling probe 100 from the customer for testingthe Pap smear sample.

The business method further includes arranging for the Pap smear testresults to be provided to the customer by communicating directly withthe customer via regular mail, electronic mail or telephone; orproviding the test results on a publicly available website where thecustomer can anonymously find the test results based on a codeassociated with the specific provided sampling probe 100 that is used bythe customer.

Now referring to the Figures, FIG. 1 is an illustration of a samplingprobe 100 held with one hand with a thumb finger on the shaft handle 210pushing the shaft 208 in the sampling probe 100 housing 200 and thebrush 242 protruding out of the sampling probe 100 housing 200. FIG. 1further illustrate how the brush 242 protrude out of the sampling probe100 housing 200 while rotating 230, when the shaft handle 210 is pusheddistally 226 into the sampling probe 100 housing 200.

FIG. 2A shows a sampling probe 100 when there is no force exerted on theshaft handle 210. Here the retracting compression spring 900 is forcingthe brush 242 at the distal end 226 of the shaft 208 back in thesampling probe 100 housing 200. A general orientation of distaldirection 226 and proximal direction 228 is identified in FIG. 2A, andadhered to throughout this disclosure and balance of the figures. Thesedirectional orientations identify the orientation of the sampling probe100 and all its components as in reference to the orientation that thesampling probe 100 assumes when it is to be used in probing a bodycavity (in this disclosure a vagina canal, not shown). The directiontowards the body cavity is designated as distal direction 226 and thedirection away from the body cavity is designated as proximal direction228. The same orientation designation carries out throughout thisdisclosure accordingly for each separate element of the sampling probe100.

Accordingly, the sampling probe 100 includes a housing 200 with a flange202 at the housing 200 proximal end 228. The housing 200 furtherincludes an internal step ring 204 and a fixed in place follower tab 206protruding from and fixed to the internal step ring 204 towards thedistal end 226 of the housing 200.

The sampling probe 100 further includes a shaft 208. The shaft 208resides inside the housing 200. The shaft 208 includes a shaft handle210 at its proximal end. The shaft 208 is configured having two mainsections. The proximal part of the shaft 208 is a solid straightproximal section 212, and the distal 226 section of the shaft is aspirally grooved distal section 214. At the distal 226 end of the shaft,the spiral groove 214 ends in a short straight groove section 216. Theouter diameter of the shaft's solid proximal section 212 is larger thanthe outer diameter of the shaft's spirally grooved distal section 214.Furthermore the outer diameter of the shaft's spirally grooved distalsection 214 is smaller than the inner diameter of the housing internalstep ring 204. Since the shaft 208 is placed within the housing 200, theouter diameter of the shaft's solid proximal section 212 is smaller thanthe inner diameter of the housing 200.

The sampling probe 100 further includes a brush 242 (refer to FIG. 2B)which is coupled to the distal 226 end of the shaft 208. The brush 242includes a brush base section 220 at its proximal 228 end and a brushbristles section 222 at its distal 226 end. The brush further includes abrush section O-ring 224 on the brush base section 220. With the brushbase section 220 of the brush 242 inside the housing 200, the O-ring iscompressed between the outer diameter of the brush base section 220 andthe inner diameter of the housing 200, preventing passage of any fluidpast the brush section O-ring 224 into the housing 200 where thespirally and straight grooved section of shaft 214, 216 is located.

The sampling probe 100 further includes a retracting compression spring900 positioned on the spirally grooved distal section 214 of shaft 208inside the housing 200. The retracting compression spring 900 islongitudinally positioned between the distal 226 end of the shaft solidproximal section 212 and the housing internal step ring 204. Theretracting compression spring 900 provides a force, pushing on thedistal 226 end of the shaft solid proximal section 212 in a proximaldirection 228, keeping the brush 242, which is coupled to the distal 226end of the shaft 208, inside the housing 200. In order to push the brush242 out of the housing 200, a force opposing the retracting compressionspring 900 should be applied to the shaft handle 210, overcoming theexpansion force of the retracting compression spring 900 pushing theshaft 208 and the coupled brush 242 in a distal direction 226.

FIG. 2B shows a sampling probe 100, when there is a distal direction 226force exerted on the shaft handle 210, causing a forward movement 232 ofthe shaft 208. Here the retracting compression spring 900 is compressedallowing the brush 242 at the distal end 226 of the shaft 208 toprotrude out of the distal 226 end of the housing 200 of the samplingprobe 100 in a forward movement 232. While the shaft 208 is moving in adistal 226 forward movement 232 direction, the follower tab 206 of thehousing 200 initially engages the short straight groove section 216 ofthe spirally grooved distal section 214 of the shaft and then engagesthe spiral grooves of the spirally grooved distal section 214 of theshaft, causing the shaft 208 and the coupled brush 242 to move in arotational movement 230 direction while simultaneously advancing in aforward movement 232. As the brush 242 exits the distal 226 end of thehousing 200 the brush bristles section 222, which has been in acontracted formation while inside the housing 200, expands. This forwardmovement 232 and rotational movement 230, while the brush bristles 222expand enables contact between the brush bristles 222 and the adjacentwalls of the body cavity (here the vagina canal, not shown,) when thesampling probe 100 is distally 226 inserted inside the body cavity andthe shaft handle 210 is pushed distally 226, to collect cell sample andfluid present in the body cavity for testing.

FIG. 2C illustrates a capped sampling probe 240. The capped samplingprobe 240 shows a used sampling probe 100 with the brush 242 inside thesampling probe 100 housing 200, with a cap 234 including preservativeliquid 238 coupled to the distal 226 end of the sampling probe 100housing 200. The preservative liquid 238 preserves the samples collectedby the brush 242 to be tested later. The cap 234 includes an O-ring 236at its proximal 228 end. The cap O-ring 236 (with the Cap 234 coupled tothe distal 226 end of the sampling probe 100 housing 200) is compressedbetween the inner diameter of the proximal 228 end of the cap 234 anddistal 226 end outer diameter of the sampling probe 100 housing 200. Thecap O-ring 236 provides a seal where the sampling probe 100 housing 200is coupled to the cap 234 and prevents the preservative liquid 238 fromspilling out of the capped sampling probe 100.

FIG. 3A shows a standalone housing 200. The distal 226 and proximal 228orientation of the housing 200 is shown, where the housing 200 includesa flange 202 at its proximal end, and an internal step ring 204 and afixed in place follower tab 206 protruding radially inward out of theinternal step ring 204 towards the distal 226 end of the housing 200.

FIG. 3B details a cross section 3B-3B view of the housing 200, showingthe internal step ring 204 and the fixed in place follower tab 206protrusion of the housing 200.

FIG. 4 shows a shaft 208 with a coupled brush 242 at its distal 226 endand a shaft handle 210 at its proximal 228 end. The shaft 208 furtherincludes a solid proximal section 212 and a spirally grooved distalsection 214. The spirally grooved distal section 214 includes the spiralgroove 218 along the spirally grooved distal section 214, and the shortstraight groove section 216 at the distal 226 end of the spirallygrooved distal section 214 of the shaft 208. The shaft 208 furtherincludes a threaded blind hole 400 at its distal 226 end, where theshaft 208 couples to a threaded stud 700 protruding out of the proximal228 end of the brush 242. FIG. 4 further illustrate a cross sectionalview of the brush 242 as coupled to the shaft 208. Brush 242 includes abrush base section 220, a brush bristles section 222, with the bristles222 in a contracted configuration, and the brush section O-ring 224.

As is illustrated in FIG. 4, the spirally grooved distal section 214 ofthe shaft 208 has a single groove 218 along the distal grooved section214 of the shaft 208. This embodiment comprising a single groove,provides for structural integrity and strength of the shaft's 208spirally grooved distal section 214 through maintaining a substantialcross sectional area of the spirally grooved distal section 214 by onlycutting a single groove at each cross section of the diameter of thespirally grooved distal section 214 along the reduced diameter sectionof the shaft 208 in comparison with the larger diameter of the solidproximal section 212 of the shaft 208.

FIG. 5 shows a bi-sectional housing 500. The bi-sectional housing 500includes two sections that are coupled to each other forming thebi-sectional housing 500. One of the two sections is a long proximalsection of the bi-sectional housing 502 and the other section is a shortdistal section of the bi-sectional housing 504.

The proximal section of the bi-sectional housing 502 includes the flange202 on its proximal end and an internal thread 506 at its distal end forcoupling to the short distal section of the bi-sectional housing 504.The proximal section of the bi-sectional housing 502 further includesthe internal step ring 204 and the protruding from and fixed to theinternal step ring 204 follower tab 206 towards its distal end.

The distal section of the bi-sectional housing 504 includes an externalthread 508 at its proximal end for coupling to the proximal section ofthe bi-sectional housing 502. When the external threaded 508 end of thedistal section of the bi-sectional housing 504 is screwed into theinternal threaded 506 end of the proximal section of the bi-sectionalhousing 502 the two sections join and form the bi-sectional housing 500of the sampling probe 100.

In a sampling probe 100 embodiment that uses the bi-sectional housing500, the brush 242 is located in the distal section of the bi-sectionalhousing 504. When a bi-sectional housing 500 sampling probe 100 is usedfor a Pap smear, the sampling probe 100 is distally inserted into thevagina canal and the handle 210 of the shaft 208 of the sampling probeis pushed in, to rotationally protrude the brush 242 out of thebi-sectional housing 500 distal end to collect cell samples. After thecell samples are collected, the shaft handle 210 is released and theretracting compression spring 900 retracts the shaft 208 and the coupledbrush 242 back into the bi-sectional housing 500.

When using the bi-sectional housing 500 sampling probe 100 for Papsmear, when the cell samples are taken and the sampling probe is outsidethe vagina canal, the distal section of the bi-sectional housing 504 isunscrewed from the proximal section of the bi-sectional housing 502, andthe brush 242, as it also decouples and unscrews from the shaft 208,remains in the distal section of the bi-sectional housing 504, asillustrated in FIG. 6A.

FIG. 6A shows a standalone distal section of the bi-sectional housing504 with a brush 242 inside the distal section of the bi-sectionalhousing 504. The brush 242 includes brush bristles section 222, thebrush base section 220 including the threaded stud 700, unscrewed fromthe shaft 208, and the brush section O-ring 224. In order to preservethe cell samples on the brush bristles 222, a cap 234, which containspreservative liquid 238, is put on the distal end of the distal sectionof the bi-sectional housing 504 with a brush 242 inside the distalsection of the bi-sectional housing 504, as illustrated in FIG. 6B.

FIG. 6B illustrates assembly 600 which is a capped distal section of thebi-sectional housing 504 with a brush 242 inside the distal section ofthe bi-sectional housing 504. FIG. 6B shows a cap 234 with preservativeliquid 238 coupled to the distal section of the bi-sectional housing504. As shown in FIG. 6B the cap O-ring 236 at the proximal end of thecap 234 is compressed between the inner diameter of the open end of thecap 234 and the outer diameter of the distal section of the bi-sectionalhousing 504. The cap O-ring 236 seals the gap between the open end ofthe cap 234 and the distal section of the bi-sectional housing 504,preventing the preservative liquid 238 from spilling from around theexternal surface of the distal section of the bi-sectional housing 504.Furthermore the brush section O-ring 224 seals the gap between the brushbase section 220 and inside of the distal section of the bi-sectionalhousing 504, preventing the preservative liquid 238 from spilling fromthe gap between the brush base section 220 and inside of the distalsection of the bi-sectional housing 504. The cap O-ring 236 and thebrush base section O-ring 224 provide for a sealed assembly 600 totransfer the cell samples on the brush bristles 222 preserved inpreservative liquid 238 to a test facility for testing the Pap smearcell samples.

FIG. 7A shows a brush 242 in thehousing 200 where the brush is coupled to the grooved 214 end of theshaft 208. In FIG. 7A the brush bristles 222 are inside the housing 200and maintain a contracted shape. FIG. 7B further shows the brushbristles 222 as expanded when the brush bristles 222 are outside of thehousing 200. FIG. 7C illustrates a standalone hemispherical brush 710with the bristles 222 expanded, the brush base section 220, the brushsection O-ring 224 and the threaded stud of the brush 700 at theproximal end of the brush 242.

In FIGS. 8A theinternal step ring 204 is not shown for clarity of illustration. FIG. 8Ashows a cylindrical bristle 800 configuration brush 242 inside thehousing 200 with the bristles in a contracted shape. FIG. 8B furthershows a standalone cylindrical bristle 800 configuration brush with thebristles expanded as it would be when the brush 242 is outside thehousing 200. FIG. 8B further identifies the brush base section 220, thebrush section O-ring 224, and the threaded stud 700 at the proximal endof the brush 242.

FIG. 9 illustrates a standalone retracting compression spring 900.

FIG. 10 illustrates a standalone cap 234 and the cap O-ring 236 at theopen end of the cap 234.

FIG. 11 illustrates a vial 1100 with preservative liquid 238 inside thevial and a vial top 1102. The vial 1100 is an alternative method forcapturing or extracting the Pap smear sample cells from the brush 242bristles 222 after the Pap smear test is done. The cell samples aredeposited into the preservative liquid 238 inside the vial 1100 bydipping the brush 242 bristles 222 into the preservative liquid 238inside the vial 1100 for several times. Once the cell samples aredeposited into the liquid preservative 238 inside the vial 1100, thenthe vial 1100 is sealed using the vial top 1102 and transferred to a labfacility for testing the cell samples.

FIG. 12 is a flow chart 1200 detailing steps for a method of use of thesampling probe 100 (see FIG. 1,) where the method is presented in step1202 as a method for taking a cervical or vaginal sample for patientwith hysterectomy for the purpose of Pap smear or detecting certainsexually transmitted diseases.

This method includes Step 1204 of distally 226 (see FIG. 2A) inserting asampling probe 100 into a vaginal canal (not shown) (see FIG. 1,) andthe Step 1206 where the sampling probe 100 comprise a housing 200 with adistal internal step ring 204 including a protruding follower tab 206,an internal shaft 208 with a handle 210 at the shaft's proximal 228 (seeFIG. 2A) end and a spiral groove 218 at the shaft's distal section, aretracting compression spring 900 inside the housing on the spirallygrooved distal section 214 of the shaft 208, with the housing protrudingfollower tab 206 engaging the spiral groove 218 of the shaft 208, and abrush 242 (see FIG. 2B) coupled to the distal 226 end of the shaft 208.

The method includes Step 1208 of pushing on the shaft handle 210 (seeFIG. 1) against the retracting compression spring 900, causing the brush242 to protrude the distal 226 end of the housing 200. With the housingfollower tab 206 engaging the shaft spiral groove 218, it causes theshaft 208 and the coupled brush 242 to rotate, and as stated in Step1210 the brush 242 is used to take a Pap smear sample.

The method further includes Step 1212 where after a sample is taken theshaft handle 210 is released, causing the retracting compression spring900 to retract the brush 242 into the housing 200. Then Step 1214follows where after the sample is taken a cap 234 is coupled to thedistal 226 end of the sampling probe 100 housing 200 (see FIG. 2C).

Step 1216 in FIG. 12 further elaborate that the cap 234 comprises anopen end, a closed end, and an O-ring 236 at the cap's open end (seeFIG. 10), and contains a preservative liquid 238 for preserving the Papsmear sample. Step 1218 further provides that the capped sampling probe240 (see FIG. 2C) is then sent to a lab for testing the Pap smear sampleon the brush 242.

Step 1220 of FIG. 12 elaborates on an alternative embodiment, where thesampling probe housing 500 (see FIG. 5) includes a two sectionsconfiguration with a short distal section 504 detachably coupled to along proximal section 502, where the long proximal section 502 includesthe internal step ring 204. When the two housing sections are separatedthe brush 242 remains in the short distal section 504, and the detachedshort distal section 504 of the sampling probe 100 housing 500 with thebrush 242 (see FIG. 6A) is capped 600 (see FIG. 6B). Here the cap 234contains the preservative liquid 238 and the caped short distal end ofthe housing with the brush 600 is sent to a lab for testing the Papsmear sample on the brush 242.

Step 1222 provide a further alternative, where a method for preservingthe Pap smear sample for lab test includes inserting the sampling probe100 brush 242 into a vial 1100 (see FIG. 11) containing a preservativeliquid 238 for preserving the Pap smear sample, then removing thesampling probe 100 brush 242 from the vial 1100, sealing the vial 1100and sending the vial 1100 to a lab for testing the Pap smear sample inthe preservative liquid 238.

Step 1224 of FIG. 12 further elaborates that a feature of using thesampling probe 100 for performing the Pap smear is that the holding ofthe sampling probe 100, distally 226 inserting the sampling probe 100into the vagina canal, pushing on the shaft 208 handle 210 and releasingthe shaft 208 handle 210 is done using one hand (see FIG. 1).

FIG. 13 is a flow chart detailing steps for a business method 1300,where the method is presented in step 1302 as a business method forproviding a sampling probe 100 (see FIG. 2A) to a customer for a fee,for taking a Pap smear cell sample. Step 1304 further elaborates thatafter the customer acquire the sampling probe 100, the customer willstart the Pap smear by distally inserting (see FIG. 1) the samplingprobe 100 into a vaginal canal (not shown).

Step 1306 further elaborates on the configuration of the sampling probe100 (see FIG. 2,) as the sampling probe 100 including a housing 200 witha distal 226 internal step ring 204 including a protruding follower tab206, an internal shaft 208 with a handle 210 at the shaft's proximal end228 and a spiral groove 218 at the shaft's distal section 226, aretracting compression spring 900 (see FIGS. 2 and 9) inside the housing200 on the spirally grooved distal section 214 of the shaft 208, withthe housing protruding follower tab 206 engaging the spiral groove 218of the shaft, and a brush 242 (see FIG. 2B) coupled to the distal 226end of the shaft 208.

Step 1308 then details the business method 1300 as the business method1300 further including receiving a used sampling probe 100, or a vial1100 containing Pap smear cell samples (see FIGS. 2C, 6B, 11) from thecustomer and testing the Pap smear sample, or arranging for a lab toreceive the used sampling probe 100, or a vial 1100 containing Pap smearcell samples from the customer for testing the Pap smear sample.

As for providing the test results to the customer, Step 1310 details thebusiness method 1300 further, as to including arrangement for the Papsmear test results to be provided to the customer by communicatingdirectly with the customer via regular mail, electronic mail ortelephone; or providing the test results on a publicly available websitewhere the customer can anonymously find the test results based on a codeassociated with the specific provided sampling probe 100 that is used bythe customer.
